Abstract
The invention relates to a test stand for the simulation of the vibration behavior of a vehicle. The test stand comprises a receiving element A for contacting with a vehicle F and an excitation system S for the application of excitation frequencies. The excitation system comprises a main actuator system H with at least one movable main actuator 10 and an additional actuator system Z with at least one movable additional actuator 20, the additional actuator system Z being connected to the main actuator system H.
